Today we welcome over 500 data engineers to our annual user conference in San Francisco and announce some exciting product launches and company milestones. ClickHouse has surpassed 4,000 customers and $250 million in annual run-rate revenue — adding over 1,000 customers in the single quarter since January and more than tripling ARR year-over-year.
This momentum and achievement is thanks to the community that has built, broken, debated, contributed to, and pushed ClickHouse forward long before there was a company to put a logo on it. Thank you.
A note on where this started #
None of this exists without Alexey Milovidov. Alexey created ClickHouse to solve a real problem, and then made the decision that changed everything: he open-sourced it in June 2016. Next month marks ten years of ClickHouse as an open-source project. A decade of contributors, maintainers, issue-filers, benchmark-runners, and production operators who took a database and made it the standard for real-time analytics. Alexey, thank you. To everyone who has committed code, filed a bug, or run ClickHouse in production over the last ten years: this milestone is yours as much as ours.
What you're building #
A year ago, "AI workloads" was a phrase people said at conferences. Now it's a category, and the work being done on top of ClickHouse is the proof. Anthropic, Cursor, Lovable, Decagon, Weights & Biases, Sierra, and Modal are building the AI products reshaping how software gets made. Polymarket and Airwallex are running markets and money flows on ClickHouse. Capital One, Visa, Cisco, Intuit, Shopify, DoorDash, Mercado Libre, Vercel, Zoox, and Jump Trading are doing things every day that, frankly, we never could have designed for ourselves. And the companies that defined the last era of software — Sony, Tesla, Meta, Memorial Sloan Kettering, Lyft, Instacart — keep moving more of their analytics, observability, and AI infrastructure to ClickHouse Cloud. The breadth is what I'm most proud of. An LLM lab and a global bank running the same engine for the same reason: when something is genuinely fast and genuinely affordable, the people who need both show up.
What we're shipping #
The pace of AI adoption has made one thing obvious: cost-performance is the new constraint. High-concurrency, low-latency, always-on workloads make raw speed table stakes. Speed without efficiency just produces an expensive bill.
That conviction shapes most of what we are announcing this week:
- ClickHouse Agents is a fully managed agentic analytics service, powered by Anthropic's Claude. It's a no-code way to ship agents grounded in your ClickHouse data, with a chat interface, sandboxed code interpreter, shareable artifacts, skills, memory, and multi-agent workflows, connecting natively to ClickHouse and any MCP-compatible system. Working with the Anthropic team to bring this to life has been one of the most rewarding things I've done as CEO.
- CostBench is an open, reproducible benchmark that applies each cloud data warehouse's real billing model to the same workload. We built it because we think customers deserve apples-to-apples comparisons. The results are at clickhouse.com/benchmarks. Please check it out and judge for yourself.
- House Mates is our first formal partner program. More than 50 partners across six continents at launch. We do what we do better because of what they build on top of us, and now we have a way to make that collaboration formal. Check it out on clickhouse.com/partners.
- Under the hood: Managed Postgres in public beta, observability for the AI era through Managed ClickStack and Langfuse, full-text search now GA, and automatic JOIN optimization that closes the last gaps with traditional warehouses.
What comes next #
We're here at our user conference Open House 2026 in San Francisco. If you're here, find us. I want to hear what's working and what isn't. If you can't make it, the talks will be online soon, and our team will be at every meetup we can get to over the next year.
A milestone is a good moment to look up. It's not a finish line. The work that matters most is what we build for the next 4,000 customers, and the 40,000 after that.
Thank you for trusting us with it.
— Aaron, Alexey, Yury
